Katsura Tree (Cercidiphyllum)


Cercidiphyllum-is a- genus-containing two- species-of plants, both commonly called-katsura. They are the sole members of the- monotypic- family-Cercidiphyllaceae. The genus is- native-to Japan and China and unrelated to- Cercis-(redbuds).The type species, Cercidiphyllum japonicum, can reach 45 m (148 ft) in height, and is one of the largest hardwoods in Asia. The other species, Cercidiphyllum magnificum, is much smaller, rarely reaching over 10 m (33 ft) in height. Cercidiphyllum produces spurs along its twigs. These are short stems with closely spaced leaves. The foliage is dimorphic. According to a recent description "short shoots bear broadly cordate or reniform, palmately veined leaves with crenate margins; long shoots bear elliptic to broadly ovate leaves with entire or finely serrate margins." Leaf size varies from 3-8 cm long and 3-5.5 cm broad. The genus is dioecious, having separate male and female trees. The small inconspicuous flowers are produced in early spring and wind-pollinated; the fruit is a cluster of 2-4 small pods, each pod 1-2 cm long with numerous small, flattened and winged seeds. The fruits mature in autumn and release their seeds in autumn through winter.
